John Ingham is now retired from Chemical Engineering at Bradford University U.K. The first of a long series of courses on the Modelling and Simulation of Dynamical Chemical Engineering Systems was begun there in 1974, sponsored by the Institution of Chemical Engineers and inspired by leave of absence at the ETH Zurich. Research areas include Liquid-Liquid Column Hydrodynamics, Extraction Process Dynamics and Biochemical Engineeering; the latter, being developed, during a further leave of absence at the GBF, Braunschweig. He is especially proud of this and the two other VCH-Wiley Modelling and
